I would love to add a 3rd front facing seat in my Thor Axis 25.2. We travel with 3 adults and it gets boring to 3rd. person. Is there a kit? I can see how the 2 seats are installed but if I add 3rd in same line it would be crammed against the dog house. I am thinking an off-set mount to have it back a ways. Also I wonder about using right seat from a truck with split bench seating in place of right seat. When I worked out of a Grumman van the size of my MH, we used a temp jump set that pinned in a pipe style mount and it was DOT ok.
